GT7 Weekly Challenge | July Week 1 | Best Cars & Tunes | Update 1.70

In this series I cover the current Gran Turismo 7 Weekly Challenges using cheap easy winners, original engine builds, swapped cars, race cars, and budget friendly setups. Some cars use multiple tunes depending on the event — including dirt setups, road race builds, and lower cost alternatives for newer players trying to complete the weekly challenges without spending millions of credits. Simple builds, easy wins, and proven tunes updated every week. 📌 My transmission is different and more effective than stock — quick guide here:    • GT7 Transmission Setup Guide | Perfect Gea...   00:00 Intro 00:19 Silvia spec-R Aero Tune 00:56 Honda Civic Si Tune 01:39 K-car Copen Tune 02:22 Yangwang U9 Tune 02:51 SF19 Honda Tune #GranTurismo7 #GT7 #GT7WeeklyChallenge #GT7Tuning #GT7Tunes #GT7Builds
